Cable fire retardant coating is a type of fire retardant coating. According to the national standard “GB28374-2012 cable fireproof coatingâ€, cable fire retardant coating refers to coating on cables (such as rubber, polyethylene, polyvinyl chloride, crosslinked polyethylene, etc. As the surface of the cable and conductor of the conductor and jacket, it has fire retardant protection and a certain decorative effect of the fire protection coating.
Fire-retardant cable coatings are generally composed of tert-acrylic emulsion water-based materials, including various fire retardants and plasticizers. When the paint coating is exposed to fire, it can produce a uniform and dense sponge-like foam insulation layer, which can effectively suppress and block flames. Spread and spread, it plays a protective role for wires and cables. Mainly applicable to fire-retardant treatment of wire and cable in power plants, industrial and mining, telecommunications and civil buildings. It can also be used for the fire protection of objects such as wood structures, metal structures, and buildings that can be combustible.
The main advantages of the cable fire protection coating are: environmental protection, non-pollution, non-toxic and odorless, and no threat to the health of the application personnel. Fire-retardant coatings for cables also have the characteristics of thin coating, strong adhesion, good flexibility, and good insulation and corrosion protection. This product is widely used in fire-retardant treatment of wire and cable in power plants, industrial and mining, telecommunications, and civil buildings. It can also be used for fire protection of objects such as wood structures, metal structures, and flammable substrates of underground structures.
At present, the cable fire protection coatings on the market mainly include water-based cable fireproof coatings, ultra-thin cable fire protection coatings, and so on. Water-based cable fire protection coating is a new type of cable fire protection coating developed with new technology. Its characteristic is that it immediately forms a uniform dense sponge-like expansion thermal insulation layer in case of fire, which can effectively isolate flame spread. Adding nano-scale inorganic water-repellent agent into the coating can form lotus beads effect on the surface of the cable. The strong water repellent feature makes the cable more secure. This kind of cable fireproof coating uses a resin with super softness as a binding agent and is coated with a cable of a fireproof coating. Under high deflection, the coating film does not crack and fall.
